Select three ratios that are equivalent to 5:2
A 2:5
B 10:4
C 20:50
D 35:14
E 55:22

B D E

Step-by-step explanation:

B: you would multiply 5 and 2 by 2

D: you would multiply 5 and 2 by 7

E: you would multiply 5 and 2 by 11

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
